CALL
TO ORDER
EXECUTIVE
SECRETARY KRAUSE: Good morning
everybody. If we could have everybody
find a chair? We're trying to get the
speakers. There are still some speakers
outside. And it's the staff trying to
get them in. So we may have to wait a
little bit later, but I think we'll go ahead and get started now. And then if everybody's not quite ready,
we'll just hold up a few minutes. But I
think we'll get the meeting started so that we can at least try to keep close
to schedule.
Good
morning, everyone. We're ready to begin
the 66th meeting of the General and Plastic Surgery Devices Panel. My name is David Krause. I'm the Executive Secretary of this
panel. And I'm also a biologist and a
reviewer in the Plastic and Reconstructive Surgery Devices Branch in the
Division of General, Restorative, and Neurological Devices.
I'd
like to remind everyone that you are requested to sign in on the attendants'
sheets, which are available at the tables by the doors just outside. You may also pick up an agenda, a panel
member roster, and information about today's meeting out there on the tables.
The
information includes how to find out about future meeting dates through the
advisory panel phone line and how to obtain meeting minutes or transcripts.
Before
I turn the meeting over to Dr. Choti, I'm required to read a statement into the
record regarding conflict of interest.
CONFLICT
OF INTEREST AND OPENING REMARKS
EXECUTIVE
SECRETARY KRAUSE: "The following
announcement addresses conflict of interest issues associated with this meeting
and is made a part of the record to preclude the appearance of an impropriety.
"To
determine if any conflict existed, the agency reviewed the submitted agenda for
this meeting and all financial interests reported by the committee
participants.
"Conflict
of interest statutes prohibit special government employees from participating
in matters that could affect their or their employers' financial
interests. However, the agency has
determined that participation of certain members and consultants, the need for
whose services outweigh the potential conflict of interest involved, is in the
best interest of the government.
"We
would like to note for the record that the agency took into consideration
certain matters regarding Dr. Miller.
Dr. Miller reported his institution's past and current involvement with
firms at issue.
"In
the absence of personal financial interest, the agency has determined that he
may participate fully in the panel's deliberations. In the event that the discussions involve any other products or
firms not already on the agenda for which an FDA participant has a financial
interest, a participant should excuse him or her self from such
involvement. And the exclusion will be
noted for the record.
"With
respect to all other participants, we ask in the interest of fairness that all
persons making statements or presentations disclose any current or previous
financial involvement with any firm whose products they may wish to comment
upon."
At
this point I'd like to turn the meeting over to Dr. Choti, the chairman.

CHAIRMAN
CHOTI: I would like to note for the
record that the voting members present constitute a quorum, as required by 21
CFR Part 14.
Let
me read a letter from Dr. Michael Olding, who was to be a member, a nonvoting
member, on this panel. He elected not
to be present and requested that the following letter be read, "Dear Dr.
Choti, I would like to request the following statement to be read into the
record at the time of the General and Plastic Surgery Panel meeting.
"On
December 2004, I agreed to serve on this panel with great enthusiasm for its
mission and with a full understanding of the commitment and the need for
impartiality. Accordingly, I completed
the required conflict of interest statement in January 2005, indicated that
there are no conflicts.
"Subsequently,
on March 21st, 2005, Medicus Pharmaceutical Corporation announced plans to
merge with Inamed Corporation, a firm at issue. That merger is subject to approval by stockholders, regulatory
approvals, and customary closing conditions according to the companies.
"Upon
learning of the planned merger, I immediately notified the Executive Secretary
of the proposed merger and that I owned a quantity of stock in Medicus.
"Initially,
on April 1st, 2005, the Executive Secretary indicated that my service on the
panel would not be affected by my stock holdings and the planned merger, but
one business day before this meeting, on Friday, April 8th, I received a fax
from Integrity Committee and Conference Management Branch informing me that due
to the stock‑holding value, between 50,000 and 100,000, in a firm that is
slated to merge with a firm at issue, I would be excluded from voting on the
panel. It does appear that I would be
allowed to 'review and discuss matters before the panel,' even though I am
denied the right to vote.
"As
the chronology demonstrates, the incipient conflict was created by the decision
of the two companies to merge and not by any action on my part. Indeed, I made the FDA aware of the
situation.
"I
was fully prepared and committed to continuing my service on the panel
impartially and a relatively small stock‑holding I have in the company,
which until March 2005 had no interest in the outcome of our work, would have
no bearing on my decision‑making process.
"I
do not feel it is appropriate for me to continue my service on the panel as a
partial member; that is, one without voting rights. Since the FDA has concluded that my voting may create an
appearance of a conflict due to my stock holdings, I do not want my continued
service as a nonvoting panel member to be suspect in any way.
"I
regret having to make this decision as I possess important experience as a
plastic surgeon for the panel to consider.
And my departure will leave only one other professional with similar
experience. But the handicap that the
FDA has placed upon me because of the incipient conflict, not of my making,
that arose since my appointment to the panel makes my decision necessary.
"Thank
you for your consideration and understanding.
And good luck to you and the panel in your important work. Sincerely, Michael Olding."
Now
I would like to introduce Commander Stephen Rhoades, the Acting Deputy Director
of the Division of General, Restorative, and Neurological Devices, who will
update the panel since the last meeting.
Dr.
Rhoades?
CDR
RHOADES: Thank you, Dr. Choti.
PANEL
UPDATE
CDR
RHOADES: I am Stephen Rhoades. I am the Acting Deputy Director in the Division
of General, Restorative, and Neurological Devices. Welcome, members of the panel, members of the public, and
manufacturers, to this important three‑day meeting of the General and
Plastic Surgery Devices Panel on two silicone gel‑filled breast implants.
Tomorrow
you will make recommendations and vote on Inamed Corporation's pre‑market
approval application. On Wednesday, you
will make recommendations and vote on Mentor Corporation's pre‑market
approval application.
Because
of the high public interest in silicone gel‑filled breast implants, in
addition to the regular public comment periods for any PMA discussion, we have
scheduled a full day for a public comment on issues related to silicone gel‑filled
breast implants.
This
panel last met on March 25th of 2004, at which time you recommended approval of
Dermik Laboratories pre‑market approval application for their Sculptra
dermal filler for lipoatrophy in HIV‑positive patients. This device application was approved on
August 3rd with a conditional post‑approval study to evaluate long‑term
safety.
On
April 22nd of 2004, FDA approved Genzyme Corporation's Hylaform dermal filler
for moderate to severe facial wrinkles and folds.
This
panel recommended approval of this device at the November 21st, 2003 panel
meeting. The approval included a
condition for a post‑approval study in patients with Fitzpatrick IV to VI
skin types.
On
August 9th, 2004, FDA issued a final rule classifying silicone sheeting for the
management of closed hyperproliferative scars as Class I devices exempt from
pre‑market notification. This
panel recommended that these be Class I‑exempt at the July 24th, 2003
panel meeting.
The
agency appreciates the commitment of the panel members. And we also appreciate the comments of the
representatives of the 30 professional organizations and 145 members of the
public who have requested time to address the panel today.
Thank
you for your attention. I would now
like to introduce Dr. Miriam Provost for a few words.
WELCOMING
REMARKS
DR.
PROVOST: Good morning. As Commander Rhoades said, I am Miriam
Provost. I am the Acting Director for
the Division of General, Restorative, and Neurological Devices.
I
would like to just take a few minutes and give everyone a brief regulatory
background followed by a discussion of why we have convened this meeting and
what are we asking you, our distinguished advisory panel, to do.
First,
some background on the regulatory status of silicone gel‑filled breast
implants. Prior to 1991, silicone gel‑filled
breast implants were sold on the market either as pre‑amendments devices,
which means they were on the market prior to May 1976, or as a 510(k)‑cleared
device.
In
April 1991, FDA issued a regulation that required all manufacturers of silicone
gel‑filled breast implants to submit safety and effectiveness data in
PMAs in order for their products to remain on the market.
Several
PMAs were submitted and presented to an advisory panel in November 1991 and
then again in February 1992. In April
1992, FDA determined that the PMAs did not include adequate safety data to
support approval. However, at the same
time, FDA believed there was a public health need to have breast implants
available for reconstruction in revision patients.
In
1992, because FDA believed it was important to provide continued availability
of silicone gel‑filled breast implants for women seeking breast
reconstruction or revision, we developed a new type of study design referred to
by industry and the FDA as an adjunct study.
Inamed
in 1998 and Mentor in 1992 are the only two companies that have received FDA
approval for an adjunct study. Inamed's
and Mentor's adjunct studies currently remain active. Both adjunct studies require five‑year follow‑up for
each patient enrolled. And there is no
limit on the enrollment of reconstruction or revision patients or on the number
of investigational sties.
Adjunct
studies are focused on the collection of safety data and do not include MRIs
screening for silent rupture. The 1992
agreements between FDA and industry also described information to be collected
in the study design to evaluate safety and effectiveness to support a PMA, the
so‑called "core study."
The
investigational device exemption, or IDE, studies are the mechanism by which
the core study data, which you will hear referenced during this panel meeting,
are collected.
Inamed
submitted and received approval for their core study in 1998. Mentor submitted and received approval for
their core study in 2000.
At
the current time, FDA has not approved any PMAs for silicone gel‑filled
breast implants. They remain
investigational devices, which means that a patient must be enrolled in an
adjunct study or an IDE study in order to receive one of these implants in the
U.S.
I'd
also like to note that in January 2004, FDA issued a draft update of our
guidance document for manufacturers of breast implants. This document is a framework for breast
implant manufacturers. And it includes
recommendations on the kind of information that FDA recommends be provided in a
PMA.
We
have received numerous comments on the draft guidance. And at the present time, we are continuing
to review the comments that we received.
Once we have reviewed the comments and made revisions, as appropriate,
the guidance document will be released in final.
It
should be emphasized that our review of the information in a PMA is not
affected by whether a guidance document for the product in question is in draft
or final form. As is the case for all
medical device applications, FDA will base our decisions on the scientific and
clinical data in the PMAs as well as the panel's deliberations and
recommendations regarding those data.
Now
for the task at hand. Inamed's PMA,
P020056, was presented previously at the October 2003 meeting of the General
and Plastic Surgery Devices Advisory Panel.
The panel recommended in a nine to six vote that the PMA was approvable
with conditions.
In
January of 2004, after considering the data in the PMA and the panel's
deliberations of the data, we determined that the PMA was not approvable
because the data did not provide a reasonable assurance of safety for the
device.
Therefore,
FDA's presentation at this panel meeting for the Inamed PMA will focus on the
additional information submitted by Inamed to address the outstanding safety
issues. The Inamed PMA will be the
panel's focus on Tuesday.
Mentor's
PMA, P030053, is being presented for the first time at a panel meeting. Therefore, FDA's presentation for this PMA
will involve a summary of all relevant preclinical and clinical data. The Mentor PMA will be the panel's focus on
Wednesday.
It
should be noted that, although the core study is the primary source of clinical
data for both PMAs, both sponsors use data and information from multiple
sources to address the key safety issues.
Based
on your own scientific and clinical knowledge, we are asking you, the panel, to
discuss the data in each individual PMA and advise us as to whether there is
sufficient information to provide a reasonable assurance of safety and
effectiveness for each device.
After
the panel meeting, FDA will continue to review the information contained in
this PMA. We will carefully consider
the deliberations and recommendations that you make during this meeting. Ultimately FDA will make a decision on the
approvability of these two PMAs.
We
will also hear a number of comments from the public today as well as on Tuesday
and Wednesday. And I want to thank the
members of the public for making the effort to come here today to present their
views on these applications.
I
want to assure everyone that the FDA will carefully listen to these
comments. And, as previously stated, we
will make our decision based on the scientific data in the PMAs and the panel's
deliberations on the data.
I
do want to remind everyone, however, that this meeting is not intended as a
general referendum on silicone gel‑filled breast implants. This panel meeting focuses specifically on
the safety and effectiveness of two individual breast implant PMAs. And the object of this meeting is to obtain
input from you, the panel, on the data in these applications. The FDA is very appreciative of your giving
of your time and expertise to accomplish this important task.
Thank
you very much. And now I'm going to
turn it back over to you, Dr. Choti.
CHAIRMAN
CHOTI: Thank you, Dr. Provost.
We
will now proceed with the open public hearing session of this meeting. All persons addressing the panel are asked
to speak clearly into the microphone as the transcriptionist is depending on
this as a means to accurate recording of the meeting.
I
would like to have the attention of all of the individuals who are registered
to speak to the panel today. You have
been given a number of correspondence regarding the order of your appearance.
Please
come to the podium area in advance so that we are not spending a great deal of
time in transitions from speaker to speaker.
And we have two podiums set up in order to alternate and for time sake. The FDA panel will direct you to the
appropriate podium.
Please
remain within your time constraints as a timer will be present to help you with
this. We have many public speakers
today. And so it is extremely important
that we stay on time.
There
is a yellow light that will flash 30 seconds before your time is up. And the red light flashes as soon as your
time is up. If you're still speaking at
that time, then I will promptly instruct you to summarize and cut off. If after ten seconds that is not done, then
I have been told that the microphone will be cut off. So please try to stay to your allotted times.
Also,
regarding your written comments, please only bring to the panel your written
comments that have been submitted or your presentation slides. No additional material, please.
We
would also like to address the issue of financial disclosure. Before the Food and Drug Administration and
the public believe in transparent process for the information gathering and
decision‑making, to ensure such transparency at the open public hearing
session of the Advisory Committee meeting, the FDA believes it is important to
understand the context of an individual's presentation.
For
this reason, the FDA encourages you, the open public hearing speaker, at the
beginning of your written or oral statement to advise the Committee of any
financial relationship you may have with the sponsor; its product; and, if
known, its direct competitors. For
example, this financial information may include the sponsor's payment for your
travel, lodging, or other expenses in connection with your attendance at the
meeting. Likewise, the FDA encourages
that you at the beginning of your statement advise the Committee if you do not
have such financial relationships.
If
you do not choose to address this issue of financial relationships at the
beginning of your presentation, it will not preclude you from speaking.
Let's
begin with the first speaker. These
individuals are the ones who have notified the FDA of their intent to testify
during the open public session.
The
first speaker, please? Thank you. Good morning.
MS.
JOHNSTON: Thank you.
OPEN
PUBLIC COMMENT
MS.
JOHNSTON: Good morning. My name is Kathy Keithley Johnston. I'm the Executive Director and founder of
Toxic Discovery, a national not‑for‑profit consumer advocacy
organization. I am also a registered
nurse. And I myself used to have
silicone gel breast implants. I have no
conflicts of interest.
I
am here today carrying the voices of thousands who have been directly affected
by the failure of the FDA to require long‑term safety studies concerning
breast implants.
We
believe the FDA made the right decision in 2004 when they decided not to
approve Inamed's silicone breast implants.
The new guidance that the FDA issued at the same time was an important
step forward, demonstrating the FDA's commitment to assure that breast implants
are safe for long‑term health studies before they allow them to be widely
sold.
I
am here today counting on you to help the FDA to adhere to the guidance
document. Silicone breast implants
should not be approved until a company can prove the safety of devices for long‑term
use. Since safety cannot be proven, we
ask you to deny the manufacturer's application.
Implant
lobbyists claim that there are over 100 studies of women with implants that
show no evidence of harm. That is
clearly and absolutely false. These
groups conveniently ignore the following studies: a study by the FDA of women with silicone breast implants that at
least found for six years that women had at least one failed breast implant,
even though they did not know it. This
is referred to as a "silent rupture."
That
same study found that 21 percent had silicone leakage outside the scar capsule
surrounding their implant. From there,
silicone could harm breast tissue, could migrate into lymph nodes and, thereby,
travel to lungs, liver, or other vital organs.
The
FDA also found that women with leaking silicone breast implants were more
likely to report fibromyalgia and other connective tissue diseases. Scientists at the National Cancer Institute
found that women having breast implants for at least seven years were twice as
likely to die of brain cancer, three times as likely to die of lung cancer, and
four times as likely to commit suicide compared to other plastic surgery
patients.
A
Canadian study found that women with breast implants for augmentation were more
likely to be hospitalized and had more physician visits than women of the same
age living in the same communities.
These
are just a few of the studies that were a serious concern about risk of
silicone leakage. Research has not yet
been done to determine exactly what chemicals leak into a woman's body and what
long‑term health consequences then results from that leakage and
migration of silicone. How can informed
consent be obtained when information is not even known by the very physician
implanting these risky devices?
Neither
Inamed nor Mentor has conducted studies of the health impact of leaking silicone
in a woman's body. Dow‑Corning
has funded one such study. In a Danish
study, Holmich claimed that leakage was not significantly related to connective
tissue disease. However, there were
only 23 women in this study with extracapsular leakage, a sample that is much
too small to provide meaningful safety data.
In fact, the study showed that women were four times as likely in that
study to report a connective tissue disease compared to women whose implants
were not ruptured. But these impressive
differences were not statistically significant because the sample was too
small.
You
would certainly think after 40 years that implant manufacturers should find
more than 23 women with extracapsular rupture.
Without a doubt, there are more than 40 in this very room today. There are hundreds of thousands of women in
this nation whose body would show you that leakage is present if testing was
provided.
Our
organization has serious concerns about the integrity of the studies conducted
by Inamed and Mentor. Patients in these
studies have informed us of their fears that they believed that their problems
with implants were never reported by their physician or the manufacturer.
In
closing, let me remind you of the duties of the FDA. First and foremost, the FDA is a public health agency charged
with protecting American consumers. The
FDA should be the consumer watchdog and not the advocate of the breast implant
manufacturer.
It
is your job to make sure that the FDA protects patient safety concerning breast
implants. This can only be done by
requiring long‑term health studies before approval and not after
approval.
It
is certainly not your job to protect the livelihood of plastic surgeons or
implant makers. Both have failed in
their promises to protect women, which will not make the situation better. It will only allow it to continue. And we ask you, please protect the women of
this nation.
CHAIRMAN
CHOTI: Thank you.
Next
speaker?
MS.
GROSS: Good morning, panel. I am Marcy Gross. I am a consultant who specializes in women's health issues. I am a member of the State of Maryland
Women's Health Promotion Council and serve on the boards of various private
health organizations.
Prior
to becoming a consultant, I worked for the Department of Health, U.S.
Department of Health and Human Services, where I was a Senior Policy Analyst
for a number of years in the Office of the Assistant Secretary for Health. And in my last position, I was the Senior
Adviser for Women's Health at the Agency for Healthcare Research and Quality,
where I served while there on the secretarial ad hoc task force on silicone
breast implants.
I
give you this resume to establish my familiarity with the issues at hand. However, I am speaking as a private
citizen. I have no financial links to
any of the applicants.
A
legacy from my six‑year tenure at AHRQ is an appreciation of the need for
a strong evidence base to support medical decisions. One of my concerns today is that an adequate evidence base for
the approval of silicone gel breast prosthesis still does not exist. Worse, a truly long‑term gold standard
study that will produce independent, objective research findings seems not to
be on the horizon.
We
do have 40 years of experience with breast implants, including 25 years when
the silicone implants were available to women, all women. They were pulled from the market for good
reason. They were associated with major
medical problems.
The
basic facts on this issue have not changed in the 14 years subsequent. First, available studies on the health
aspects of silicone gel implants are still short‑term and are often
produced by companies that manufacture the devices or materials.
Second,
the work that is available, some from FDA itself, indicates that the rate of
complications of implantation, reinfections, reoperations, and other adverse
events are sufficiently high to remain a major concern, despite advances in
materials.
Third
‑‑ and this is a change from the past ‑‑ the Mentor
applicant agrees that the devices will not last indefinitely and warned women
that they should expect to have them replaced.
So the issue becomes one of sequencing in looking at the data. Do we get the data first and approval after
or the reverse?
Letting
women be living testers I find highly objectionable since these are elective
procedures and there are alternatives, especially since the data on
improvements in the quality of life for patients undergoing implantation are
weak by accepted research standards and most especially since it is expected
the devices will fail and will have to be removed.
On
this last point, the overall failure rate, it should be noted that Mentor
acknowledges that their devices will have a finite in vivo life, which means,
really, that all will fail and need to be surgically removed. We just don't know when.
I
would assert that if this were an NIH‑funded research study, it's
unlikely it would go forward.
CHAIRMAN
CHOTI: Please sum up for us.
MS.
GROSS: Yes, please. I just ask that you have the data in hand before
you reintroduce the silicone breast implants.
Thank you for your time.
CHAIRMAN
CHOTI: Thank you.
Let
me remind the audience that speakers have three minutes unless it's a national
organization. And then it's five
minutes.
Yes,
next speaker?
MR.
SCHULTZ: Good morning. My name is William Schultz. I am representing a group of women's
organizations led by Command Trust. I
appreciate being given five minutes.
Thank you.
Thank
you for the opportunity to address this Committee on the very important
question of whether FDA should approve the applications for silicone gel breast
implants. For the record, I have no
financial ties to either of the applicants.
Congress
enacted the medical device amendments in 1976 in the wake of several tragedies,
including the Dalkon shield IUD, which killed 16 women and injured countless
others. Congress sought to remedy the
defect by a new law, the defect being that medical devices were being marketed
without any demonstration of their safety or any adequate testing.
Congress
was particularly concerned about the safety of implantable devices. The basic showing that it required
manufacturers of these devices to make was that there was a reasonable
assurance that the device was safe and effective. In the case of breast implants, efficacy is obviously not the
issue. Instead, the issue is safety.
If
you think about it, for a therapeutic product, such as a heart valve, the
safety standard entails a weighing of risk versus benefits to health. And so FDA may approve a product with
substantial risks if it finds the benefits are even greater.
But
for a cosmetic product, which is what we have before us today, there are no
therapeutic benefits. For these
products, the law does not allow approval if the product is associated with
significant risk or even if there is significant uncertainty about safety. And I think that is a very important
principle to keep in mind as we go through the next three days.
It
is also relevant that the manufacturer has the burden of proof. Where there are doubts or uncertainties,
then the product may not be approved because the manufacturer has not carried
its burden. The law does not
contemplate that the patients or consumers should bear the risk of unanswered
questions.
At
the October 2003 Advisory Committee meeting, there was discussion of various
approval conditions and post‑market studies. First, the Committee should understand that any approval
conditions are not enforceable by FDA.
Once the agency approves a product, then physicians are allowed to
deviate from restrictions on the use of the product. And FDA has no authority to enforce those restrictions.
Second,
while post‑market studies may be useful, they cannot substitute for the
basic safety standard in the statute.
The statute does not provide that the agency may approve a product now
and allow the demonstration of safety at a later date.
At
the last Advisor Committee meeting, there was also discussion about whether
women should have the option or the choice of using breast implants as long as
they were fully informed.
Although
Congress has adopted the buyer beware approach for dietary supplements and in
other areas, this was not the approach that it adopted for medical
devices. Instead, for these products,
it has declared in law that medical devices are not to be available until the
manufacturer has demonstrated safety.
It is this Committee's charge to do its best to apply that law.
Congress'
approach has two important benefits.
First, it means that patients and consumers can be confident of the
safety of device products that they use.
It also creates an important incentive to the manufacturers to design
their products to meet the high standard that Congress established.
Significant
questions have been raised about the safety of breast implants. I'm not going to address those. But it's important, of course. These products are going to be in the body
for many years. Even though the
manufacturers have known about the standards of the statute for more than 25
years, we don't really have long‑term data. And given the extremely high breakage rate of these products,
lack of long‑term data raises serious problems.
In
January 2004, FDA determined that the evidence was not adequate. And the question that this Committee must
look at is whether the companies have produced additional data that is
sufficient to justify approval.
In
conclusion, approval of silicone gel breast implants without an adequate
demonstration of safety would have two very unfortunate consequences. First, we would have lost the opportunity to
require that these products be adequately tested.
And,
perhaps even more important, such a decision would send a message to other
product manufacturers that the door has been open for approval of medical
devices that do not meet the safety requirements established by law and that
patients will suffer.
Thank
you very much. And good luck.

CHOTI: Thank you.

DR.
HELMAN: Hi. Good morning. I'm Susan
Helman from Florida. I have paid my own
way here because I feel that this panel needs to hear from women like me.
I
had breast implants for 15 years and suffered greatly. My implants ruptured. And after numerous surgeries to remove
silicone from my body, the last surgeon stated, "There is no way to remove
it all, Susan. It's migrated to all
your tissues, your organs. It's
everywhere." Silicone as well as
platinum was found in my cheek cells, bone marrow, and lymph nodes, also in my
urine and in my blood.
My
urine platinum levels when measured eight years after explantation were 25
parts per billion, which is within the range of patients receiving chemotherapy
agent cisplatin. The urine platinum
level in the general population is .04 parts per billion. So mine was more than 500 times greater.
The
platinum ion in my urine and in my tissues I found was the exact match to my
implants that they studied as well. My
body is full of ionized platinum with no known way to remove it.
As
you know, the CDC has identified platinum as a suspected toxin. Because of my ruptured implants and the
resulting exposure to silicone and platinum, I have been diagnosed with MS and
lupus and fibromyalgia and scleroderma among many other things.
And
I'm sick. And I can't get health
insurance. When I need it the most, I
can't get it. I don't want anybody else
to suffer this way. I get severe
disabling headaches and nausea when I am exposed to exhaust fumes or unusual
odors of any kind, and I never had this problem before ever.
I'm
also concerned about young women of childbearing age and their children. I've heard that platinum can be transmitted
in milk. And I have platinum in my
urine. So, you know, I see no reason
why it couldn't be in breast milk.
Any
mother would be heartbroken to find out that during a cosmetic surgery,
unbeknownst to her, it caused her breast milk to be adulterated and cause
injury to her newborn child.
I
just ask that before implants are considered safe, platinum testing be done on
a random sample of women with silicone gel breast implants and on women with
implants, the breast milk of women with implants.
And,
in closing, please, please, please vote against the gel‑filled breast
implants until you're sure that the benefits far outweigh the risks. The first oath a doctor learns is do no
harm.
Thank
you.

DR.
GLICKSMAN: Mr. Chairman and members of
the panel, my name is Dr. Caroline Glicksman.
And I am reading the testimony from my patient Valerie Hartwell, a 45‑year‑old
mother of 3 who is unable to attend today because of work requirements.
"I
would like to advise the Committee that I have no financial relationships with
anyone connected at this meeting. I had
silicone breast implants for two years.
I had them put in because of a chest wall deformity I was born with that
caused a considerable and noticeable depression along the sternum on my right
side.
"The
size of one of my breasts was considerably smaller than the other, causing me
to be extremely self‑conscious my whole life. I would not wear bathing suits or shirts with a neckline lower
than my collarbone because my deformity was so obvious.
"I
am so thrilled that I had the silicone implant option available to me. It has made a dramatic difference in my self‑esteem. My self‑confidence has improved
drastically.
"I
have one anatomical implant on the defective side, which has helped with the
depression along my sternum. The other
implant is round, to create uniformity.
I have had absolutely no side effects.
"My
breasts remain soft and natural‑looking, which is very important to
me. They feel natural as well. I am able to sleep comfortably in any
position. I have had no problem with
hardness and no dimpling.
